# RC Time Constant

## A charging capacitor rapidly builds up charge at first but quickly slows down as it approaches its maximum capacity.

Levels are CK-12's student achievement levels.
Basic Students matched to this level have a partial mastery of prerequisite knowledge and skills fundamental for proficient work.
At Grade (Proficient) Students matched to this level have demonstrated competency over challenging subject matter, including subject matter knowledge, application of such knowledge to real-world situations, and analytical skills appropriate to subject matter.
Advanced Students matched to this level are ready for material that requires superior performance and mastery.

## RC Time Constant

Students will learn about the RC time constant and how to solve various problems involving resistor-capacitor circuits.
